GAS PRODUCER Filed Nov. 2. 1920 horizontal track 11 which rests and Patented Dec. 16, 1930 UNITED srrss; ArtNr oFFicE JOHN F. ROGERS, OF CLEVELAND HEIGHTS, OHO, ASSIGNOIR T0 Tlf-IEY WELLIVIAN ENGINEERING COMPANY, 0F CLEVELAND, OI-IO, A CORPORATION OF OI-IO AS PRODUCER Application led November 2, 1930.

This invention relates to gas` producers, and in certain respects is an improvement over the construction shown in my Patent No. 1,572,040, granted February 9, 1926.

In that patent I have shown a gas producer' with a rotatable body portion which is supported from below, and with the ash-pan Journaled on the lower central tubular support of the producer body, and though the ash-pan is normally caused to rotate with the producer body by the column of ashes eX- tending from the latter into the pan, provision is made for automatically and at intervals causing the panto rotate at a different speed than the producer body so that the column of ashes is forced downward by the relative movement between the producer body and ash-pan, causing a disintegration of the clinkers, and preventing to a large degree the formation of pipes or channels within the fuel.

lfVith the invention constituting the subject matter of the present application, the ashpan is actuated in a manner similar to that briefly referred to above, and the same results as regards the downward feed of the column of ashes and disintegration of clinkers is obtained, but in a more satisfactory manner. Further the invention involves certain differences and improvements in the construction, especially in the manner of supporting and actuating the ash-pan.

The invention may be briefly summarized as consisting in certain novel details of construction, and combinations and arrangements of parts which will be described in the specification and pointed out in the appended claims.

The ligure of the drawings is a vertical sectional View of a gas producer having one embodiment of my invention which operates very satisfactorily and with high efficiency.

In the drawings, 10 represents the rotary `body or shell of the producer which is supported on a plane above the ash-pan through the medium of a horizontal or substantially turns on supporting rollers 12 carried by stationary columns 13, there being preferably three of Serial No. 421,221.

the latter and three of the rollers 12, although only two are shown.

Any suitable means may be provided for rotating the producer body, but in this instance this is accomplished by a pinion 14;, mounted on a vertical shaft 15 and adapted to be driven by any suitable mechanism, not shown. At the top of the producer body ther-e is a stationary cover 16, there being the usual water seal 17 between the cover and the upper part of the producer body. The cover is generally provided with fuel feed mechanism, and suitable means will be provided for operating a poker such as indicated at 18, but as the inventiondoes not reside in these parts they are not illustrated.

At the lower part of the producer body there is an annular blast ring 19, and beneath this blast ring and lsecured to it there is a blast delivery member in the nature of a spider having acentral hollow hub 196, an outer flange ring 20, and a number of hollow arms 21, generally three in number by which air, steam, or both are delivered from the central hub 196 to the blast ring 19, and from the latter through suitable ports 19a into thev fuel. At the top of the hub, and secured the-reto are the usual blast hoods 22.

Depending from the peripheral orannular portion 20 of the spider there is an inwardly tapered flange or skirt 23 which extends down into the ash-pan, presently to be referred to, this,` flange or skirt being preferably composed of arc-shaped segments and being corrugated or composed of angularly disposed intersecting flat faces 23a and 236 which have an important function in forcing the column of ashes downwardly and breaking up the clinkers, when a relative movement takes place between the producer body and the-ashpan, the ring 20 and skirt 23 forming the lover end portion of the wall of the producer bo Shrine distance below the producer body there is a hollow stationary base 24, composed in this instance of several members, although this is not material to the present invention,` and rotatably supported on the bearing support 24a at the top of this base through the medium of ball bearings 25, there is a casting in the form of a sleeve 26, the lower portion of which has a flange fitting into the bearing supporting part 24a of the base, and the upper part fitting around the flanged lower portion of the spider hub 19?) so as to form with the hollow base 24: a vertical conduit 27 through which there may be supplied to the blast delivery member composed of the ring 20, arms 2l and hood 22, air, steam, or both, as is customary in the operation of gas producers. hook or latch 28 extending from the spider hub 192) into the sleeve, and this causes the sleeve 26 to rotate with the spider and with the producer body, though the sleeve is supported independently of the spider hub on the bearing support 24a of the base 24C.

The ash-pan indicated by the numeral 29 isV positioned below the producer body and mounted on the vertical conduit 27, which conduit connects with the blast delivery meinber and forms a part of the blast delivery means. This ash-pan has a central hub or sleeve-like portion 30 which fits about the sleeve 26,V and at the bottom it has a flange which rests upon the flanged lower portion 3l' of the sleeve 26 so asto be supported by it, the hub 30 of the ash-pan being normally' movable with the sleeve 26 but capable of relative rotation with respect thereto.

Thus it will be seen that the producer body is supported wholly independently of thev lower structure including the ash-pan and the parts associated with it, and that the ash-pan is supported independently of the producer body on the'sleeve 26 which rotates with the producer body, but is supported onthe stationary base beneath it. Due to the fact that the ash-pan is supported on the rotating sleeve 26, and due to the column of ashes which normally extends downward from the producer body into the ash-pan, the ash-pan` tends to, and normally does rotate with the producer body and at the samerate as the lat:y ter.

To cause the ash-pan to rotate at predetermined regularly occurring intervals at a different speed than the producer body, I secure to the lower flanged portion 31 of the sleeve 26, a bevel gear 32 which extends downwardly and outwardly from the flange 31, and I mount in a boss 33 on the bottom of the ash-pan 29 a rotary horizontal shaft 34 having at its inner end aI relatively small bevel pinion 35 which engages the gear 32, and havf ing at its outer end a star wheel 36'. This star wheel is adapted to engage and to be rotated by stationary pins 37, 'one of which is shown in the drawing, and a number of which will be mounted about the producerin the path of movement of the star wheel so that as the producer is rotated, at intervals depending upon the number of pins 37 (thenumber can be varied to suit the requirements) the. star wheel will be turned, causing the small It will be observed that there is a at the same rate as the producer body, and

each time the star wheel engages and is turned by one of the pins 37, the movement .of the Y ash-pan, is automatically slowed down, though it will continue to move in the same direction that the producer body is moving.

kllhen this occurs, the column of ashes is crowded downward beneath the tapered flange or skirt 23 atthe lower part of the producer body, and due to the corrugations or relatively inclined portions ofthis flange the clinkers are disintegrated as explained in my prior patent above referred to. Y

In order to provide a positive means for breaking upl clinkers and preventingl any hanging of the ash bed, I provide one or more `ash engaging members or plows 38 which ex-l tend inside the flange 23 vand are so disposed vas to extend into the space inside of the flange 23 and into the ash pan space. In this case I have shown Aonly one such ash engaging member,but more than one maybe provided if desired. Preferably this ash engaging member or plow 38 is secured to a projection 39?L on a fla-nge'39 which extends outwardly Vand downwardly over vthe ,upperportion ofv Ail() the sleeve 26 and the liub'30of `the ash pan.

The ash engaging member or members, as the tween the ash pan and the ash engaging mem'- ber, positively break up clinkers and prevent hanging lof the bed vof ashes. It will be obvious that the same effect may be obtained if the ash engaging member or-members, such up and thereby assist in vits downward flow1 into the ash panfrom which it is removed byv a suitable plow.

GenerallyV a suitable. plow, no t shown, willy be utilized to cause the delivery of the V ashes from the'ash-,pan as it is rotated.

I believe it is novel with me to provide in a gas producer, an ash-pan support such as i. herein illustrated, and the various features of this novel construction I wish to cover inthe appended claims not only with, but also independently of the mechanism by which thepan is at intervals automatically caused to be rotated at a different speed relative to the speed of the producer body.

case may be, will upon relative rotation be- I do not desireto be connedl to theexact details or arrangements of parts herein shown, but aimin my claims to cover allmod- .ifications which'V do not involve'a departure from the spirit and scope of my invention as defined in the appended claims.
